There are not just two sexes

How does one define intersex?

It is difficult to answer this because we do not have precise definitions for male and female.  Without  the discursive power of modern biomedical technology, intersex would not exist at all, because in past centuries the majority of people who were intersex did not even know it since the modern technology necessary to determine it did not exist.  It is a quest specific to our modern societies, armed with the required technological innovations, that is determined to define the "true" sex of every human being.  Personally, I find this search (or so called "research") to determine the "true" sex of every individual ridiculous, because it is something that we cannot define. Once we feel we have found the precise definitions for male and female, new technologies emerge which reveal even more variations and exceptions.

I disagree. There are 2 sexes. But there is a fine spectrum inbetween. Thats were intersex happens to be.

Not a 3rd sex, its just a biological fact that an intersexed body can be inbetween the sexes. And the gender of that person can be either male or female.

(just my opinion)
